Rear triangular plate
Sorry, not sure if the technical name for it, but y'all know what I'm talking about. Here's my question - I know that everyone says it provides structural integrity to the rear running gear. I can see that being the case, at least the front half of the plate that bridges between the wheel carriers. But has anyone ever tried driving without this plate? I recently reinforced the rear end with a 1" aluminum bar and noticed a real difference in the rear end tightness with high g turns. So this makes me wonder whether these reinforcement bars are actually better at controlling "splaying" of the rear suspension better than the plate and would facilitate ditching the thing. That would leave linear motion at play (front to back) but I don't know if that would actually happen since the virtual A frame struts (notably the track arm) would control this.
No real reason to remove the thing other than it was a bit of a pain to get lined up while reassembling the rear end. Asking more out of curiosity. Sent from my POCOPHONE F1 using Tapatalk |
Ike, if you put the weight of the rear axle on it's wheels without the triangle, you may risk trowing off the rear alignment.
The support bar its supposed to be installed along with the triangle (top..??) |

The suspension uprights actually move apart with the plate is removed, and often require the use of a small ratchet strap to pull them back in to reinstall the plate. It can be torqued with the vehicle still in the air.
If the car has been up in the air and the suspension unloaded while the plate was off, usually realignment is not necessary. But if the car has been set on the ground, or driven with it off, alignment is required. |

If we’re talking about the subframe uprights they are very fragile. If you drove with the plate off I’d inspect the uprights for cracks. Especially if it’s an early Boxster with thinner uprights.

Out of curiosity, why don't you want it there? Sent from my SM-G970U using Tapatalk |

That plate really strikes me more as a flex plate then a structural member - it's horribly thin and I can bend it with bare hands. I figured that my 1" square aluminum bar would stabilize side to side movement but I was concerned about fore and aft as well as diagonal stresses that the rear encounters during high g turns, which obviously a single bar will not brace for.
